There is a strong theoretical basis for the theory of original sin, if we are willing to see original sin not as a physical act, rather, a symbolic act. Original sin is thus: Once a sin has been committed, other sins will surely follow, the damn has been breached and Pandora’s Box is now wide open.
As we expand the time limit we are slowly breaking up the old routine, understanding it and replacing it with new habits, eventually we will replace it with healthy habits.
The reason why we start with low time limits and build up from there is to give the monkey time to adapt to being deprived of the smoking habit.
Sometimes we give in to the urge, especially for that oh so holy first cigarette of the day, other times we get the urge to smoke and something gets in the way, an important phone call perhaps, long enough for the urge to pass.
On our first time unit we may use any trick in the book to keep ourselves from smoking that first cigarette.
Before we light up our first cigarette of the day, how long waiting is long enough? How long are we supposed to wait before we light up?
